internal storage

[merve04]

I know its been disscussed, i read through 15 pages of this problem. I've looked up this issue on several sites, I'm having no luck. I've lost the internal storage on my device. I've tried every tip i found, I'm still not getting anything. I've tried several roms to see if using the format of the storage would have any better success, I've tried 3 different computers, 3 different usb cables. I've done the whole rename folder, unplug and replug the damn thing 30 times, the best I can get is a drive letter showing up in diskmanagement but with no media = no format option. If anyone knows anything that I might now, please let me know.
Thanks
